Gantz, Hellsing, Blood +, Another, Genocyber (probably the goriest anime of all time tbh.), Pet Shop of Horrors, Devilman, Perfect Blue (this one scared me a lot when I was a kid), Berserk (the anime is pretty tamed compared to the anime), Mirai Nikki, Paranoia Agent, Mnemosyne, Kurozuka, Narutaru (manga>anime), Ichi the Killer (make sure to watch the anime and not the live-action movie, though the movie is better IMHO.), Shigurui, Riki - Oh, and Kite are the only anime I can think of atm. Some of them are creepy and not that gory, some of them are super gory but not that creepy, and some just kind of have a mixture of both elements. I'd also recommend Evangelion b/c there are some honestly disturbing scenes in that but it's also an anime you have to be patient with.

I'm currently watching Clannad After Story and its making me all depressed and stuff like that lol because it's sad. Its really throwing my feelings of balance.

After that I'm going to watch Kaiba and Another. I should have watched Kaiba a long time ago but I got distracted.

I also gave up on watching Nanoha and SAO sadly, its not that I didn't liked them, i just didn't have the motives to finish them. I might try to finish them later.

This summer, I'm try to get my older sister (who doesn't have am account on FF) into PMMM, she said that she was going to watch a lot of anime this summer. I also plan on convincing her to watch Soul Eater, Clannad, and whatever anime I get into.
